Patented July 28, 1931 UNITED STATES PATENT OFFICE FREDERICK B. HAMMANN, OF BALTIMORE, IvIARYLAND, ASSIGNOR TO WILLIAM W. VARNEY, OF BALTIMORE, MARYLAND WIND MUSICAL INSTRUMENT PAD Application filed July 12,

The object of my invention is the providing in wind, or other, instruments pads of a resilient character and moisture-proof characteristics.

A further object of my invention is the providing an improved pad of a resilient character of a durable nature to prevent vibration and to form a tight fit.

A further object of my invention is the providing an improved instrument pad of a simple construction and ease of manufacture.

A further object of my invention is the use of a spongy material of a water-proof nature in the construction of a wind instrument pad. I

A further object of my invention is the providing a pad and an improved means of securing the same in the instrument.

A further object of my invention is the providing a pad of a spongy nature having a smooth operating face extremely resilient and of a water-proof character and practi cally indestructible.

A further object of my invention is the providing a key pad substantially indestructible and that will withstand the cutting tendency of the wind-instrument valve or key seat upon which it operates, substantially fitting the same, and of quick response to action.

I/Vith the foregoing and other objects in view, my invention consists of the novel construction, combination and arrangement of parts as hereinafter specifically described and illustrated in the accompanying draw ings, wherein is shown the preferred embodiment of my invention, but it is understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings of the herein-described embodiment of my invention, Fig. 1 shows a viewvin elevation of a saxophone; Fig. 2 is a sectional view taken through 2 2 of Fig. 1 showing an enlarged View of my improved pad as applied in the key of a windinstrument, the key and pad being seated on the valve or key seat. Fig. 3 is a plan view of the improved pad showing smooth face 1924. Serial No. 725,587.

thereof partially broken away to show the spongy center; Fig. 4 is a side view of the pad shown in Fig. 3; and Fig. 5 is a sectional view showing a modified form of the key for securing the pad therein, that might be desirable in some cases.

Similar numerals refer to similar parts throughout the several views.

1 is the saxophone or wind-instrument body; 2 is the key of a wind-instrument; 3 is my improved pad the face 4: of which is preferably a smooth and continuous surface; the interior 5 is preferably of a spongy nature to insure the desired resilience. 6 is the valve or key seat upon which pad 3 seats.

In the modified form shown in Fig. 5, key 2 is provided with a flange 7, or turned-over edge, to more securely hold the pad in position, as might be desired in some cases.

In the ordinary construction of pads for wind instruments they are made out of leather padded with wool, or other material, cork, or other pervious material. I have discovered that a water-proof face with a resilient backing forms a very much improved pad. I have also discovered that sheet sponge rubber, socalled, having a smooth vulcanized face, is ideal to accomplish the functions desired in my improvement. Ordinary rubber washers, or pads, are eir tirely too rigid, entirely too inflexible on their faces and have not been at all successful; but I have discovered that with extreme resilience of light sponge rubber, with a super-imposed smooth face, all being water-proof and integral, makes a very dcsirable combination to accomplish the purposes of my invention. I cut out pads, preferably somewhat larger than the key to which they are to be attached, and secure the same in the key by means of ordinary rubber cement, or other suitable adhesive; in many cases no adhesive at all is required.

In certain makes of instruments provided with a centrally securing device my very resilient pad, provided with a hole much smaller than the head of the securing device, is easily slipped over the same and forms a very satisfactory combination.

My pads are manufactured to fit almost every make of instrument of the types suggested above and have been found to act almost instantaneously in use, with a slight movement of the key forming a tight closure impervious to moisture, maintaining its shape during long continued use, that is, preventing deep-seated valve impression on the pad, thereby causing sluggishness and vibration. My pad is very durable andis extremely easy to re-place, when desired.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A pad for a key of a wind-instrument consisting of a face of relatively smooth, moisture proof-material incombination with a relatively spongy backing ofsubstantially the same material.

2; A musical; instrument key pad consisting of a water-proofi surf-ace made integral.
